JAMEQ BRODIE,. O.F SAN FRANCISCQCALIFORNIA.
\ Lam Patent No.r 93,801, ma August 17, 1869.
IMPRCVED STEADY-REST FOR LATHES.
The Schedule referred to in these Itters-Patsnt and making part of the same.
To all whom it 11mg concern Be it known that I, JAMES BRODIE, of the city and county of San Francisco, State of California, have invented a new 'and improved Lathe-Rest; and I hereby declare that the following is a full, clear, and exact description of the same, reference .being had to the accompanying drawing, which forms a part of this specification. 4 y
In the drawings-'- Figure 1 is a front elevation, and
Figure 2, a side elevation.
To enable othersskilled in the art to make and use my invention, I will proceed to describe fully its construction and operation.
A represents a stand or steady-rest, provided with a circular orifice, in which is attached the annular plate B, in such manner as to revolve freely.
The plate B is plovided with the adjustable dogs C O and C C', the two former of which consist of thel slotted strips c1, pivotedto the plate Bby nuts, which are provided with projections having screw-threads,
on which the nuts c'l are screwed, and hold the dog in position.
1) D represent screw-bolts, which pass through thev The screw-bolts E' pass through the outer ends of the guides E, being journalled therein, and passing from thence through the outer ends of the dogs C', terminate at the centre of the slots, instead of passing through the pivoting-bolt, as in the former case.
The dogs C O are situated directly opposite each other, as are also the dogs C C.' By this method the dogs are easily adjusted to the work, by turning the bolts, which are provided with squareheads.
When it is desired to hold the blank in an eccentric manner, the dogs C C, which are pivoted for the purpsc,are swung to-oue side, as shown by dotted lines in fig. 1, and the dogs C' C' so regulated as to form a suitable eccentric bearing. f
I am aware that the use of a revolving-rest, journailed in an upright steady-rest, is not new, .ueither do I desire'to claim the idea in itself, as the patent of E. S. Gardner, September 1, 185?, shows a similar device; but
What I dov claim as new, and desire to secure by Letters Patent, is- The dogs G C and C C', arranged and operated as described, in combination with the revolving plate B, substantially as described.
JAS. BRODIE.
